"We got nearly 100 samples from the Central Bureau of Investigation (CBI) and submitted our reports after DNA examination to the court," Dr J Gowrishankar, director, Centre for DNA Fingerprinting and Diagnostics (CDFD) told The Times of India.
Dr Gowrishankar said to what extent the court relied on the scientific evidence submitted would be known only after one goes through the judgement. The special CBI court in Ghaziabad on Monday held the Talwars guilty of the murder Aarushi, their daughter, and their servant Hemraj on May 15-16, 2008. Their sentence was pronounced on Tuesday.
Though the CDFD, an autonomous organisation funded by the Department of Biotechnology (DBT), ministry of science and technology, played an important role in providing DNA evidence in the double murder case, a large number of samples were also examined by the CFSL in New Delhi. Dr Gowrishankar said a staff of the CDFD was also cross-examined in the court about the evidence that was submitted. There was, however, a question about one of the pieces of evidence that was submitted by the CDFD.
"There was an interpolation in labelling of one of the pieces that was sent to us for DNA examination. This was later corrected," Dr Gowrishankar said.
It may be mentioned here that a senior technical examiner with CDFD S P R Prasad had deposed before the sessions court in Ghaziabad with regard to the DNA evidence that the CDFD had to provide. He clarified to the court that the labelling of two pillow covers had been interchanged and a clarification was submitted to the CBI.
